kientzle fa748c4160 Merge r687-689,691,693-701,720 from libarchive.googlecode.com:
Translate getdate.y into C for portability.  Make the get_date()
function easier to test as well:
 * Have it accept a time_t "now" to use as a reference so that test
   code can verify relative time specifications against known starting
   points.
 * Set up default date after parsing the string so that we
   can use the specified timezone (if any) instead of the local
   default.  Otherwise, local DST makes it almost impossible to
   reliably test time specifications such as "sunday UTC"
